This piece of research deals with an interestingly observed interdisciplinary challenging educational issue associated with children\'s learning performance phenomenon in classrooms. more precisely, it addresses an answer for the critically challenging educational question : how any of the students could focus on teachers\' interactive speaking in noisy environmentally overcrowd class?. more signals resulting in CPE at classroom. By the end of this paper, some interesting simulation results presented after taking into account the comparative studies of two essential ANN parameters namely : learning rate and gain factor values. Versus varying neurons\' number of the hidden layer associated to self-organized ANN paradigm model. These results revealed the effect of interrelation between various learning rate values against different values of signal to noisy ratio considering student\'s selective responsive attention.
